M. style inverter drives for the range of 1 through 5 horsepower, 200-230 VAC. A parts list and illustrations are also included. For more information on how to size these units to particular applications, please refer BALDOR Inverter Applications Manual GENERAL DESCRIPTION The BALDOR Series 11 adjustable frequency Ac drives are designed to provide adjustable speed control of conventional three phase induction motors. The method of control is accomplished by a static conversion of the fixed frequency single or three-phase AC supply into an adjustable frequency adjustable voltage output to the three-phase induction motor These microcomputer based Pulse Width Modulated(WM)inverter drives have standard adjustment features that allow tailoring of the motor/inverter system to fit a wide variety of application requirements including variable torque, constant torque, andconstant horsepower applications MOTORS Either one of the following two basic motor categories can be used with the BALDOR family of inverter drives 1. Any standard three-phase AC induction motor designed to operate at standard line frequency and fixed speed operation (speed determined by the load applied to the motor) provided the following natural occurrences are considered a. A slight increase in motor losses will occur when operated on a power source with subharmonics in the output power wavEiorm. All motor controllers that approximate a sinewave by electronic switching of a DC source will have subharmonics present in the output power waveform The motor' s capabi to produce continuous torque(typically NEMA rated torque at rated motor horsepower) must be derated as a function of the minimum continuous operating speed due to the reduced ventilation of the integral motor cooling fan. Where applications require 100% rated motor torque(constant torque application) at speeds below half rated speed, a separately powered constant air flow ventilation blower should be considered When a separately powered ventilation blower is used, a temperature sensing device should be built into the motor and connected to the control wiring to shut the motor down whenever an over temperature condition exists within the motor CAUTION: An automatic reset device should never be used in cases where an automatic restart of the motor could cause personal injury or harm C. Motors that will be operated above nameplate speed should have special consideration for mechanical suitability of the motor. Special consideration of the bearings, rotor balance, internal cooling fan construction, etc. may be needed. Please consult the motor manufacturer for more specific details on your particular type of motor and application requirements d. Motors that will be controlled by a PWm style inverter operating from a 460 VAc RMS power source will require special insulation between adjacent coil windings phase insulation) within the motor to prevent phase to phase shorts. By the nature of the power conversion within the PWm controller, the motor terminals will see approximately 650 VDC peak. This elevated voltage level will eventually cause phase to phase shorting within the motor if proper precautions are not taken 2. Any three-phase induction motor specifically designed for adjustable speed operation by an inverter type of motor control MODEL TYPES The BALDOR Series 11 inverter drives are available in horsepower ratings from 1 through 5 HP and various input voltages as shown in Table 1. the controllers are available in open chassis form for mounting into existing control cabinets and OEM use. The enclosed versions carry a NEMA 1 enclosure rating and are equipped with three knockouts suitable for attaching standard 3 /4 inch conduit fittings. Optional NEMA 4 and NEMA 12 enclosures are available through your local BALDOR stocking distributor. All BALDOR Series 11 inverters are complete functional motor speed controllers requiring only fused input power and a suitably sized three-phase AC induction motor to form an adjustable speed drive system. Remote operation and computer control are available by the addition of external control devices and connection to the onboard control terminal strip 5 TABLE 1.

Operation Modes 2 Speed, 4 Speed, External Thermal Trip STANDARD FEATURES Fault Trip Indication: Whenever an appropriate internal or external situation exists to cause a fault condition within the inverter, the inverter output will be shut off and an open collector transistor at control terminals 1 and 2 will conduct to give an external indication of the fault occurrence. A visual indication as to the type of fault will be shown via fault codes on the led display located on the front panel of the inverter a red LEd located on the lower right hand side of the inverter main circuit board will illuminate to indicate a fault condition. the open collector transistor has a maximum input voltage of 24 Vdc and a maximum current carrying capacity of 50 maDC. A trip condition can be reset internally by momentarily pushing the reset button or externally by commanding Forward and Reverse movement simultaneously. Instantaneous Power Failure Protection (Auto Restart): The inverter output will be shut off if the dc bus of the converter section drops below 61% of normal for more than 15 mSec. If input voltage is restored before the end of 15 mSec. the inverter will resume normal operation from the frequency specified by the Reduced Frequency At Instantaneous Power Failure parameter. When input voltage is reduced below 61%but still greater than 46% of normal for more than 15 mSec. the fault trip circuit will be activated and the open collector transistor at control terminals 1 and 2 will conduct to give an external trip indication for lack of input voltage If the input voltage is reduced below 46%of normal or removed and then reapplied with the RUN/STOP switch in the RUn position and the selection of manuallauto restart parameter is set at", the inverter will start the motor as if a run command has been initiated. This command sequence is known as auto Restart and no external trip indication will be given CAUTION: If an automatic restart of the motor could cause personal injury or harm. the Auto restart function should be defeated Overcurrent Trip: The inverter output will be shut off when the output current of the controller exceeds 200% of rated current. The fault trip circuit will be activated and the open collector transistor at control terminals 1 and 2 will conduct to give an external trip indication External Thermal Trip: The inverter output will be shut off whenever an open circuit condition exists at control terminal 10 with respect to control terminals 5 or 8. Closing this circuit is usually accomplished with an externally mounted normally closed thermostat. The fault trip circuit will be activated whenever an open circuit is sensed, then the open collector transistor at control terminals 1 and 2 will conduct to give an external trip indication. The External Thermal Trip function will only operate when the inverter is in the External Thermal Trip mode of operation Regenerative Overvoltage Trip: The inverter output will be shut off when the voltage of the dc bus is higher than 23% above normal. The fault trip circuit will be activated whenever an overvoltage condition exists on the DC bus. The open collector transistor at control terminals 1 and 2 will conduct to give an external trip indication This type of fault condition is usually due to an overhauling load on the motor output shaft during periods of deceleration causing the motor to regenerate energy back into the motor controller. This trip condition can usually be corrected by extending the deceleration time Overvoltage Stall Prevention: During periods of deceleration the decel time will be extended whenever an impending Regenerative Overvoltage trip is sensed. Total decel time will be multiplied by the value set by the Stall Decel Magnification parameter whenever an impending Regenerative Overvoltage trip is sensed. The total decel time with Overvoltage Stall Prevention is the product of (Decel Time)X (Decel Magnification) X(Stall Decel Magnification) Self Diagnosis Trip: The inverter output will be shut off and the open collector transistor at control terminals 1 and 2 will conduct to give an external trip indication when any of the following occur a. A malfunction of the microcomputer is detected b. The inverter will trip for safety whenever the max output frequency is changed c. The inverter will trip for safety whenever a change is made to the operation mode Digital Display: A digital display is mounted to the front of the inverter to give a visual display of set-up parameters, operation mode, output frequency, and fault diagnostics Controlled Reversing: The motor shaft rotation can be reversed by shorting control terminal 9 to terminal 5 or 8. the shorting of the control terminals is usually accomplished by an external switch closure. The ability to electronically reverse the motor shaft rotation eliminates the need for external reversing contactors. When a controlled reversal is commanded, the motor will dec alerate down the decel ramp to zero speed and then accelerate up the accel ramp in the reverse direction us Voltage Present Indicator: A red LEd is I cated on the lower left hand side of the ir. erter main control board. this LEd is used o give a visual indication that voltage is present on the DC bus. When voltage is present on the dC bus the LEd will illuminate CAUTION: Do not rely on the Bus Voltage present indicator to determine when the unit is safe for maintenance or service. Always wait at least 5 minutes after disconnecting input power before beginning any internal servicing of this equipment. Regenerative and DC Dynamic Braking Motor braking is available for stopping or short duration holding. The standard braking torque is 20% of the motor's full load torque. Units equipped with a braking resistor have an available braking torque of 70 to 100%of the motor's full load torque 10 Adiustable skip Frequencies: Two fully adjustable frequency skip zones are available to minimize mechanical resonance. In some applications certain inverter output frequencies may cause a mechanical resonance to develop in the driven motor load, By skipping these inverter output frequencies the machine mechanical resonance may be avoided. The frequency skip zones are selected by specifying the continue frequency and the jump frequency. Selectable 4 Speed Operation: Two modes of operation available from the BALDOR Series 1 1 is a selectable 4 speed mode. One of 4 independent speeds is selected by appropriate external switch closures connected to the inverter control terminals 10 and 11 with respect to control terminals 5 or 8. Other operation modes include 2 Speed Operation and External Thermal Trip. Independent Accel/Decel Rates: Each selectable speed has an independent accel/decel rate adjustment. The time of accel will equal the time of decel for each selected speed The rate of decel for a Stop command is independent from all other accel/ decel rates. The actual rate of accel/decel is the product of(Accel Decel Time)X(Accel Decel Magnification) Actual stopping time may vary depending on the inertia of the driven load ADJUSTMENTS Base Frequency: The Base Frequency parameter sets the point on the V/F curve where the voltage output of the inverter becomes a constant value with increasing output frequency. The base frequency is adjustable within the range of 30 to 250 Hz in 221 steps Carrier Frequency: The PWM carrier frequency input to the internal inverter control scheme is adjustable within the range of 868 to 1420 Hz in 8 steps. The PWM carrier frequency can be adjusted to minimize audible noise Volts/Hertz VF)Ratio: The BALDOR Series 1 1 has a fully adjustable v/F ratio. The V/F ratio is set from the factory to be a linear function for constant torque applications and can be adjusted to a squared reduced relationship for variable torque applications. The Base Frequency parameter can be adjusted to give constant horsepower from a properly sized AC induction motor throughout the entire speed range Maximum Output Frequency: The maximum output frequency is set from the factory at 60 Hz. The maximum output frequency can be set to 120 Hz via a dip switch located on the lower right hand side of the main control board to allow the motor to be driven at twice the motor's rated speed. Please consult the motor manufacturer for suitability to run at a speed higher than the nameplate rating Upper And Lower Frequency Limits: The upper and lower frequency output of the motor controller can be set to limit the adjustable speed range of the driven motor. This feature is useful in application where a minimum or maximum motor speed is desired regardless of the input command signal 11
